Test if A's rotation equals B's rotation, within a tolerance. Preferred over "A.GetRotation().Equals(B.GetRotation())" because it is faster on some platforms.
static bool AreRotationsEqual ( const [TTransform](API\Runtime\Core\Math\TTransform)< T > & A, const [TTransform](API\Runtime\Core\Math\TTransform)< T > & B, [FReal](API\Runtime\Core\Math\TTransform\FReal) Tolerance )
